In a statement, MBI-GluckShaw co-founders Paul Bontempo and Clark Martin described the decision as "logical," given the wide client base and their Statehouse experience.

“We couldn’t be happier to come to this agreement with Pete," according to the statement. "Both of us have worked with him for more than 20 years. We are excited that our two firms have merged, bringing additional talent to what already is the largest-staffed such firm in Trenton.”

MBI-GluckShaw represent a large number of corporate clients, including American Express, Coca-Cola and Verizon, as well as nonprofits, municipalities and professional associations.

Insight's clients include the Council of Teaching Hospitals, the Hospital Alliance of New Jersey, which represents urban medical centers, and the National Coalition of Alcohol and Drug Dependence.

“My team’s joining forces with MBI will create an all-inclusive firm, which will provide expert counsel to many different industries at all levels of government. I am very excited about our growth prospects,” Lillo said in a statement.
